I '4 of the shell is provided with pro'ections 'This shell is made of a resilient material such as rubber, rubber reinforced with'a fabric or l other filler, or the like. In4 the drawings, the

shell is illustrated as being made of one layer of rubber. It is to be understood that it ma be formed of twoor more layers, as desire The signalmay be made in any desired shape. I have obtained satisfactory results when the shell 1 is substantially triangular in cross-l shell and imbed or inlay it in the face of the shell. This construction. will form a smooth A si yso made will be cleaned by rain or water used in s rinklin the roadway thereby keepin it c aan an legible.v

-The she may be secured to the base in `l4any suitable manner. For instance, it may be secured thereto by some suitable cement.

Or, if desired, i't may be directly vulcanized n thereto. 'i In thedrawings still another mannerofattachin the` shell to the base is illus-- trated. Accor 'ng to the latter, the bottom gr plu 5 which cooperate with oles 6 is forme in a base 7 made of metal or any other suitable material.' The holes 6 are shaped as illustrated in Figure 2, that is, wider at the bottom thanat the top thereof. By means "of ythe plu y 5 bein ofthe base ,the she `to the base.- -If desired, a sheet of vrubber 8 forced in theholes 6 1 is securely anchored ma be dis sed on the bottom of the base 7, sai sheet v ing united to the ends of the plu l5.. This'tends tomake the anchorin of t el shell to the base more secure, thoug it is not essential.l Y The base 7 is preferably formed so that it 4 is sli htly larger in size thanthe bottom of the s ell. In each of its .corners the base is provided lwith -a' hole 9 which is adapted to receive means whereby the signal may be securely and removablyfastened'in orto a roadway. -In the case of stone or concrete surfaced streets or roads,lholes disposed in direct alignment. with the holes 9^of the base 7 are drilled. By vplacing expansible sleeves 10 t 'y within the holes and threading bolts'll therein, the si al is firmly secured to the roadway. p en `the signal is to be fastened to the surface of a road or street which is not covered with concrete, I have found it advisable to place `short sections of ordinary 12 'in the street or roadway, said pipes ing 1 disposed directly beneath the holes 9 of the base 7. After the pipe' is in position in the ground, it is filled with concrete in which, before it sets, the expansible sleeve 10 is placed. The bolt 1l is screwed through the hole 9 of the metal base down into the expansible member 10, said member having become firmly embedded inside of the pipe 12. This manner of securing the signal to the roadway is simple and easy. It in no way damages the roadway. If at some time the'v tained withinl the interior of the shell is' .l

permitted to escape during compression and to allow the return of air after compression to aid the' signal inassuming its normal condition. To attain thisobject holes 13 are disposed in the sides of the shell. It is to be understood that any desired number of holes located in any suitable place may be used, the single hole disclosed in the drawing being merely illustrative. Instead of the holes 13 Suitable valve mechanisms may be used. If desired, the interior of the shell may be filled either in whole or in part with a sponge rubber or other resilient filler 14.

The signal above described comprises a hollow shell suitably secured to a base. It is within the sco e of this invention` to use a compressiblean /or resilient' member, hollow or otherwise, for the hollow shell described.

From the above it is apparent that I have provided a'traliic signal which attracts and commands attention. It is easy to apply and remove from the roadway. Due to its construction, it is capable of withstanding abuse without any substantial injury to itself or to the vehicle coming in contact therewith. The mannerin which it is secured to the roadwa does not damage or injure the latter. I after its installation, removal thereof becomes necessary, no substantial damage to the roadway is done. `The entire damage consists of a few small holes which may be filled up very cheaply.

Since it is obvious that various changes may be made in the specific details above described'without departing from tlie nature of the invention', I do not intendto limit myself thereto except as defined in the appended claims. f Y

I claim 1. A trafilesignal comprising. a hollow compressible member having a legend thereon, resilient means within said member to aid said compressible member to assume its normal shape after being compressed, and means to secure said member to the roadway.

2. A traic signal comprising a hollow resilient shell adapted to be compressed by vehicles passing thereover, said hollow shell being provided with a passageway therethrough to permit the escape of and return of air from and to the interior thereof during and after said compression, resilient means in said shell to aid said shell to assume its normal shape after being compressed, and means to secure said shell to the roadway. v

3. A trailic signal comprising a hollow shell of resilient material, plugs of resilient material extending from the bottom of said shell, a base having a plurality of holes adapted to receive said plugs whereby said shell is anchored to said base, and means to secure said base to the roadway.

4. A traiiic signal comprising a hollow shell of resilient material, plugs of resilient material extending from the bottom of said shell, a base having a plurality of holes adapted to receive said plugs whereby said shell is anchored to said base, and means to secure said base to the roadway, said shell bein `substantially triangular in cross-section an having one face thereof parallel to said roadway and. another face bearing a legend thereon inclined thereto.

5. A traffic signal comprising a hollow shell of resilient material adapted to be compressed by vehicles passing thereover, said shell being-provided with a passageway to permit the escape of and return of air from and to the interior of said shell, plugs extending from the bottom of said shell, a base having a plurality of'holes adapted to receive said plugs, whereby the shell is secured to said base, and means to secure said base to the roadway.

6. A traf'c signal comprisin a hollow shell of resilient material adapte to be compressed by vehicles passing thereover, said shell being provided with a passageway tok permit theescape of and return'of air from and to the interior of said shell, plugs of resilient material extending from the bottom of said shell, a base havin a plurality of holes adapted to receive sai plugs, whereby the shell is secured to said base, and means to secure said base to the roadway, said shell being substantially triangular in crosssection and having one face thereof parallel to said roadway and another face bearing a legend inclined thereto.

7 A traiiic signal comprising a substantially enclosed hollowshell made of resilient material and adapted to be compressed by ve'- hicles passing thereover, said shell being provided with a passageway therethrough to pery mit the escape of and return of air rom and to the interior thereof during and after said compression, porous resilient material substantially filling the interior of said shell, and means to secure said shell to the roadway.

8. A traffic signal comprising a substantially enclosed hollow shell made of resilient material and adapted to be compressed by vehicles passing thereover, said shellbeing provided with a passageway therethrough to perl mit the escape ofand return of air rom and to the interiorthereof during and after said compression, sponge rubber substantially lill- SISv
